Technical data
| Stator/Rotor core |
Stator/Rotor core
Laminated and enamel-insulated on both sides to minimise eddy-current losses.The stator winding is made of flat copper or round copper wire depending on the machine size. The completely wound stator pack is thereby impregnated in an epoxyresin VPI. The subsequent heat treatment hardens the resin. |
| Rotor |
Rotor
Squirrel cage rotor type.Depending on machine size, the rotor construction is either a solid shaft or welded ribbed shaft. The rotor winding can be either a pressure die cast aluminum or a copper bar construction. |
| Bearing |
Bearing
General dataAntifriction bearings grease lubricated (ball or roller type) or oil lubricated sleeve bearing. The theoretical lifetime of bearings, L10h according to ISO 281/1 standard, of standard horizontal construction generators, without external forces (radial and / or axial) is in excess of 50.000 hours. On request, the lifetime of bearings, L10h can be in excess of 100.000 hours. Locating bearings are on the D end side and floating bearings on the ND end side. Both bearings are fitted with a regreasing system. The used grease is removed through a valve locked in the outer bearing cover. Sleeve bearings available as an option. On request special bearings are designed where high radial and axial forces are applied. |
| Impregnation system |
Impregnation system
Stator and rotor are VPI treated with an unsaturated polyester amide resin which is polymerisation in oven. |
| Insulation system |
Insulation system
Stator: F class insulated with a synthetic enamel.(H class insulation available on request) |
| Protective treatments |
Protective treatments
Dedicated protective enamel is applied on the winding. |
